Abstract
PURPOSE: To obtain weld beads of uniform depth of penetration and a broad sectional shape by applying alternating magnetic fields to the arc generated from a nonconsumable electrode of which the sectional shape near the leading end part is approximately a rectangular shape, thereby oscillating the arc in the long side direction of the electrode section and controlling the shape of the weld beads.
CONSTITUTION: In the sectional shape near the leading end part of a nonconsumable electrode 2, the direction approximately perpendicular to the weld line direction is made the long side of a rectangular shape section, and the width thereof is formed approximately equal to the diameter (d) of the circular section of the electrode. The long side end part thereof is beveled as shown by a symbol (r), to make the arc easy to oscillate. The weld line direction X-Y is made the short side of the rectangular section and the width thereof is set at (t). Next, alternating magnetic fields are applied from a magnetic controller 7 to the electrode 2 of this shape in the arrow 8 direction, thereby oscillating the arc in the arrow A-B direction. Since this welding method controls the arc smoothly by the slight change in the magnetic fields while maintaining the arc constant, the depth of penetration in both end parts of beads is positively assured.
